Graph Search is currently available only on the U.S. English version of the site. The searches are done through the standard search bar at the top of the screen.

The wider capabilities are being rolled out slowly to "a small group of people who currently have Graph Search," Facebook said. It didn't say when it will be offered more widely, but it said it will improve the service through feedback.

The wider search capabilities should make it easier for Facebook users to find people with common interests, by searching through a larger set of information.
